首先发明这个算法的人肯定是对那个什么Threaded Binary Tree烂熟于心啊;其次,对inorder遍历也是理解透彻啊。。。 再次,这人思维肯定特清晰。 Reference:http://www.geeksforgeeks.org/inorder-tree-traversal-without-recursion-and-without-stack/
A binary tree isthreadedby making all right child pointers that would normally be null point to the inorder successor of the node (ifit exists), and all left child pointers that would normally be null point to the inorder predecessor of the node. 把所有原本为空的右子节点指向了中序遍历之后...

Given abinary tree, return theinordertraversal of its nodes' values. 知识点: Recursion Iteration Threaded binary tree 二刷: 要求的iteration: 最初做法: class Solution: def inorderTraversal(self, root: TreeNode) -> List[int]: if not root: return [] ans = [] stack = [root] l = [0]...
In-Order Traversal for above example of binary tree is I - D - J - B - F - A - G - K - C - H 2. Pre - Order Traversal ( root - leftChild - rightChild ) In Pre-Order traversal, the root node is visited before the left child and right child nodes. In this traversal, th...
Binary trees are generally used in dictionary machines =-=[17]-=-. X-trees. Most of X-trees introduced by Despain and Patterson [11], e.g., threaded X-trees (having maximum degree 4) and ringed X-trees (having maximum degree 5) are full binary tree based interconne......

Morris traversal is a traversal technique which uses the concept of threaded binary tree and helps to traversal any binary tree without recursion and without using stack (any additional storage). In this article we discuss Morris Traversal for inorder binar...

In this method, we have to use a new data structure-Threaded Binary Tree, and the strategy is as follows: Step 1: Initialize current as root Step 2: While current is not NULL, If current does not have left child a. Add current’s value ...
